wireless audio streams. Further, an audio system for transmitting wireless audio streams
is provided. In particular, a method and audio system for transmitting wireless audio
streams to hearing system(s) are provided.
BACKGROUND
[0002] Wireless communication to and from hearing devices has been increasing in continuation
of the developments within wireless communication technology. In a crowded environment
where audio is distributed to the crowd, for example in an airport or in a movie theatre,
it is known to stream audio via a telecoil solution having a limited bandwidth with
limited possibilities of separating different audio streams.
[0003] Further, audio streams from neighboring broadcasting areas, such as cinema auditoriums
of a cinema complex, may overlap requiring a receiver device to be able to separate
and distinguish between audio streams.
SUMMARY
[0004] Despite the known solutions there is still a need to personalize and listen to different
audio streams that are transmitted wirelessly in a crowded environment.
[0005] There is also a need for a user of a hearing system to be able to in a simple and
effective manner personalize and select desired audio streams.
[0006] Accordingly, an audio system for audio streaming is provided, the audio system comprising
a radio system comprising one or a plurality of stationary transmitter units configured
to transmit at least a first audio stream with first audio identification data indicative
of the first audio stream and configured to transmit at least a second audio stream
with second audio identification data indicative of the second audio stream. The plurality
of transmitter units includes a first transmitter unit and a second transmitter unit
and the audio system comprises a communication unit for transmitting configuration
data for the hearing system. The communication unit is configured to receive a request
indicative of at least one audio track; determine configuration data for the hearing
system, e.g. based on the request indicative of at least one audio track; and transmit
the configuration data to the hearing system for allowing or enabling the hearing
system to receive at least one audio stream representative of the audio track indicated
in the request.
[0007] Also disclosed is a method for operating an audio system for transmitting wireless
audio streams to a hearing system, wherein an audio stream is an electromagnetic signal
representative of an audio track. The audio system comprises a communication unit
and a radio system comprising one or a plurality of stationary transmitter units for
transmitting at least a first audio stream with first audio identification data indicative
of the first audio stream and optionally a second audio stream with second audio identification
data indicative of the second audio stream. The plurality of stationary transmitter
units includes a first transmitter unit and a second transmitter unit. The method
comprises receiving, e.g. in the communication unit, a request indicative of at least
one audio track; determining configuration data for the hearing system e.g. based
on the request indicative of at least one audio track; and transmitting the configuration
data to the hearing system for allowing or enabling the hearing system to receive
at least one audio stream representative of the audio track indicated in the request.
[0008] The method and audio system provides simple configuration of hearing device receivers
for effective audio streaming in multi-stream environments such as airports or cinema
complexes. Further, the method and audio system enable power saving in hearing devices
by reducing the requirements for data sent from the hearing device.

DETAILED DESCRIPTION
[0010] The disclosed audio system and method allows the radio system to broadcast several
audio streams, each audio stream having different audio identification data. By the
present method a hearing system is able to search for and receive only a desired audio
stream. Upon receipt of a request indicative of an audio track, the communication
unit determines and transmits configuration data indicative of at least one audio
stream representative of the audio track requested to the hearing system, allowing
the hearing system to play the audio track requested.
[0011] The hearing system may comprise a hearing device and optionally an accessory device.
Thus, transmitting configuration data to the hearing system may comprise transmitting
configuration data to a hearing device and/or an accessory device of the hearing system.
Transmitting configuration data to the hearing system may comprise transmitting configuration
data as an email, a text message, e.g. an SMS. The hearing device of the hearing system
may comprise a processor configured to compensate for hearing loss or disability of
the hearing device user.
[0012] The configuration data may allow or enable a hearing system to setup or control the
wireless receiver of the hearing device in order to receive or listen for audio stream(s)
representative of the requested audio track.
[0013] An audio track is an audible signal, such as an airport call, a movie sound track,
speech, and/or a piece of music.
[0014] An audio stream is an electromagnetic signal representative of an audio track. A
transmitter sends one or more audio streams. An audio stream comprises audio stream
data and audio identification data, the audio stream data being representative of
an audio track. Audio identification data (audio ID) is data enabling identification
of or used for identification of a specific audio stream.
[0015] Audio identification data (audio ID) may comprise one or more of transmitter ID,
transmitter group ID, audio group ID, audio type ID, and audio protocol ID.
[0016] Transmitter identification data (transmitter ID) is data enabling identification
of or used for identification of a specific transmitter of the radio system.
[0017] Transmitter group identification data (transmitter group ID) is data enabling identification
of or used for identification of a group of transmitters of the radio system. A group
of transmitters comprises a plurality of transmitters. Transmitters may be grouped
based on audio track, position within a selected area, etc. A first group of transmitters
may be formed by transmitters streaming the same audio track but with different audio
ID.
[0018] Audio group identification data (audio group ID) is data enabling identification
of or used for identification of a group of audio streams relevant for the user of
the hearing system. Audio group ID may comprise data indicative of audio track or
parts of an audio track (audio track ID). Audio group ID may comprise data indicative
of language. Audio type identification data (audio type ID) is data enabling identification
of or used for identification of audio type. Audio type ID may be representative of
hearing device models/manufacturers able to listen to the audio stream in question.
[0019] Audio protocol identification data (audio protocol ID) is data enabling identification
of or used for identification of audio protocol, such as encoding format, frequencies,
key for decrypting or decoding the audio streams, or other physical properties of
an audio stream.
[0020] An audio track (e.g. a movie sound track) may be broadcasted using a group of a plurality
of transmitter units, i.e. a plurality of transmitter units may transmit the same
audio stream data with different audio ID. A plurality of transmitter units streaming
the same audio stream data increases the capacity and increase the possibility of
a receiver to receive a reliable signal. Each transmitter unit of the group of transmitter
units broadcasts an audio stream identifiable by audio ID. The group of transmitter
units may be identified by common transmitter group ID broadcasted as part of the
audio ID.
[0021] A transmitter unit may comprise one or more antennas. A transmitter unit may be configured
to stream a plurality of audio streams simultaneously. This may be achieved e.g. by
a transmitter unit comprising a plurality of antennas.
[0022] The configuration data may comprise audio ID or parts thereof. In particular, the
configuration data may contain information identifying a transmitter unit transmitting
the requested audio stream (transmitter ID). Alternatively or additionally the configuration
data may contain information of a group of transmitters (transmitter group ID), e.g.
to enable a hearing device to select the optimum audio stream (transmitter), such
as the transmitter providing the audio stream with the best signal to noise ratio.
[0023] Hearing systems may be different, depending on e.g. model or type. Therefore the
configuration data may comprise first configuration data for a first hearing system
model or type and second configuration data for a second hearing system model or type.
The hearing system may thus choose the configuration data suitable for the particular
hearing system. The configuration data may comprise at least third and/or fourth configuration
data suitable for different hearing systems/models. Transmittal by default of more
than one configuration data may provide support for several types or models of hearing
systems without requiring the hearing system to transmit additional information to
receive a suitable configuration data. Thereby simple request data are enabled.
[0024] Transmitting configuration data from the communication unit to the hearing system
may be performed in several different ways.
[0025] For example, the communication unit may comprise a wireless transmitter for transmitting
the configuration data to a hearing device and/or an accessory device of the hearing
system. The wireless transmitter may be configured to transmit the configuration data
to a hearing device or an accessory device of the hearing system. Alternatively or
additionally, the communication unit may comprise a near field communication device
configured for transmitting configuration data based on the request indicative of
an audio track to the hearing system. The communication unit may comprise a web server
adapted to transmit the configuration data to a hearing device and/or an accessory
device of the hearing system.
[0026] Several other possibilities of transmitting the configuration data are present e.g.
Bluetooth transfer or by use of an accessory device such as a hearing device remote
control or a smartphone.
[0027] The communication unit may comprise a near field communication device configured
for transmitting configuration data to a near field communication device of a hearing
system. When the hearing system is in close proximity of the near field communication
device of the communication unit, e.g. within 40 cm or within 20 cm or within 15 cm
or within 5 cm, a near field communication tag of the hearing system receives the
configuration data transmitted by the near field communication device of the communication
unit. The hearing device/system may configure receiver parameters corresponding to
the received configuration data in order to receive at least one audio stream representative
of the audio track requested. The near field communication device of the audio system
may be configured to receive and/or send configuration data at a frequency in the
range from 13 MHz to 14 MHz.
[0028] The communication unit may comprise a wireless transceiver or transmitter, thus allowing
the transmittal of configuration data to be performed using a wireless protocol.
[0029] In an exemplary communication unit, the configuration data may be transmitted wirelessly
at one or more frequencies, e.g. in the range from 2.4 GHz to 2.5 GHz, in the range
from 800 MHz to 1 GHz, in the range from 3.6 GHz to 3.7 GHz, in the range from 4.9
GHz to 5.9 GHz and/or in the range from 13 MHz to 14 MHz.
[0030] The communication unit may comprise a unit allowing transmitting configuration data
by sending a text message, such as an SMS or email, to a mobile phone of the hearing
system. Accordingly, the request may comprise a phone number and/or an email address.
[0031] The radio system may comprise a radio system control unit connected to the transmitter
units and configured to control the transmitter units. The radio system control unit
may further be connected to the communication unit to enable the communication unit
to obtain information regarding the audio streams from the radio system.
[0032] The radio system control unit may be configured to determine configuration of each
of the transmitter units, and decide which audio stream data to stream from which
unit. Further the radio system control unit may control the audio ID to be transmitted
as part of the audio stream, e.g. by sending a control signal to the respective transmitters.
[0033] The request indicative of an audio track, e.g. received at the communication unit,
may be received from different sources depending on the audio system in question.
The audio system may comprise a user interface unit connected to the communication
unit. The user interface unit may be configured to receive a request indicative of
at least one audio track and transmit the received request to the communication unit.
The user interface unit may receive the request from a user of the audio system. The
user interface may comprise one or more of a touchscreen, a keyboard, a mouse. The
user interface may comprise a monitor or other display, including LED display, plasma
screen, OLED display.
[0034] Alternatively or additionally the communication unit may receive the request from
the hearing system or a user via e.g. the internet, a local area network, a phone
line or a near field communication device.
[0035] In an exemplary audio system, the request indicative of at least one audio track
may be transmitted to the communication unit by a user sending a text message such
as an SMS containing the request.
[0036] The request indicative of at least one audio track may comprise hearing system data.
The hearing system data may contain information of the hearing system such as model
of the hearing device, type of hearing device, if there is an accessory device, type
of accessory device, phone number and email. This may allow the audio system to transmit
the configuration data in several ways. It may also provide the audio system with
the possibility to transmit configuration data specific to the hearing system from
which the request was received.
[0037] The audio system may comprise a database unit configured for storing or comprising
audio track, audio stream data and/or audio ID. The database unit may comprise configuration
data for the radio system, e.g. in the form of a lookup table.
[0038] The database unit may be connected to the communication unit. Upon receiving a request
indicative of an audio track, e.g. at the communication unit, determining configuration
data for the hearing system may comprise searching the database unit for configuration
data corresponding to the requested audio track.
[0039] The database unit may be connected to the radio system, for example via the radio
system control unit. The radio system may transmit data to the database unit containing
information of the current state of each transmitter unit. Information transmitted
from the radio system to the database unit may for example contain information on
audio streams being currently transmitted, audio ID, audio group ID, transmitter ID,
transmitter group ID, etc.
[0040] Alternatively or additionally the database unit may be configured for storing or
comprise radio system configuration data. Thus, the radio system may retrieve data,
from the database unit, indicative of contents to be transmitted at the transmitter
units.
[0041] The database unit may also be connected to the user interface unit. The user interface
unit may transmit data to the database unit, indicative of controlling the transmitter
units of the radio system. The radio system may then retrieve information from the
database unit on e.g. audio stream, audio ID, audio group ID etc. to transmit from
the transmitter units.
[0042] The communication unit may also or alternatively be configured to transmit configuration
data based on the request indicative of at least one audio track to an accessory device
of the hearing system. Communication between the accessory device and the communication
unit of the audio system may be via the internet, a phone line, a local area network
or other techniques. The accessory device may subsequently be able to transfer the
configuration data to the hearing device, thus enabling the hearing device to receive
at least one audio stream representative of the requested audio track and play the
audio track represented by the received audio stream.
[0043] The accessory device may be e.g. a mobile phone, a tablet computer, a smart phone,
a hearing device remote control unit or a key card.
[0044] The method for operating an audio system for transmitting wireless audio streams
may comprise transmitting at least one or a plurality of wireless audio streams with
respective audio ID from a transmitter unit of the radio system. The method comprises
receiving a request indicative of at least one audio track and transmitting configuration
data based on the request for at least one audio track to at least one hearing system.
[0045] Receiving the request indicative of at least one audio track may comprise receiving
a request indicative of at least one audio track at the communication unit.
[0046] The configuration data may comprise at least a part of audio ID of an audio stream
representative of the requested audio track.
[0047] In an exemplary method, the radio system assigns audio ID to each audio stream. The
radio system transmits the audio ID to the communication unit. When the communication
unit receives a request indicative of at least one audio track, the communication
unit transmits configuration data based on the request indicative of at least one
audio track to a hearing system. The hearing system receives the configuration data,
configures the hearing device according to the configuration data, and receives the
corresponding audio stream from the transmitter unit of the radio system, thus enabling
playback of the audio track represented by the audio stream data.
[0048] The method may comprise transmitting the configuration data from the communication
unit to the hearing system via a near field communication device in the communication
unit and a near field communication device in the hearing system.
[0049] In an exemplary method, transmitting the configuration data may be achieved by having
the hearing system in close proximity to the near field communication device of the
communication unit. A choice of a plurality of near field communication devices of
the communication unit may serve as a way of selecting the audio track to request.
[0050] Transmitting configuration data to the hearing system may comprise transmitting configuration
data to an accessory device of the hearing system, such as e.g. a mobile phone, a
tablet computer, a smart phone, a hearing device remote control unit or a key card.
[0051] In an exemplary method, the communication unit transmits the configuration data to
an accessory device, e.g. via a phone line, over the internet, via a local area network
or via a near field communication device. The accessory device is then able to transmit
the configuration data to the hearing device. Hereby, a power consuming pairing procedure
between the hearing device and the audio system is avoided or at least simplified.
[0052] The audio stream may be transmitted at selected frequencies e.g. at a frequency in
the range from 2.4 GHz to 2.5 GHz or at a frequency in the range from 800 MHz to 1
GHz. Other suitable frequencies may be in the range from 3.6 GHz to 3.7 GHz and/or
in the range from 4.9 GHz to 5.9 GHz
[0053] The figures are schematic and simplified for clarity, and they merely show details
which are essential to the understanding of the invention, while other details have
been left out. Throughout, the same reference numerals are used for identical or corresponding
parts.

communication unit 4 enables the hearing system 6 to configure the receiver/transceiver
of the hearing device 6A in order to receive and select the audio stream representative
of the audio track requested in a simple and power efficient way. Thus the hearing
device 6A is enabled to play the requested audio track, e.g. after signal processing
to compensate for the hearing loss or disability of the hearing device user.
[0056] The communication link 14 between the radio system 8 and the communication unit 4,
enables the communication unit to obtain radio system information, thereby determining
configuration data corresponding to the audio streams 16, 16', 16", 16"', of the transmitter
units 10, 10', 10", 10"' and the request indicative of at least one audio track 11,
received from the hearing system.
